Chilling footage shows two teenage killers fist-bumping as they celebrated stabbing a man to death after luring him to a park over sexual messages he had sent to a 17-year-old girl.
Danish Mansha, Rimsha Tariq, and Daiyaan Arif, all aged 18, scoured the internet to find someone they believed wanted to have violent sex with women.
They tricked their first victim, Sohail Ali, 29, into coming to Summerfield Park in Birmingham by the promise of meeting a girl on December 4 last year.
He had been speaking with Tariq online before agreeing to meet with the girl in the park at 2.30pm.
